A-M Systems 16-Channel Extracellular Amplifier with Headstage Model 3600

A-M Systems is proud to introduce our new Model 3600 16-Channel Extracellular AC Amplifier with Headstage.
In response to many inquiries for a larger version of our popular Model 1800 2-Channel Microelectrode AC Amplifier, we have developed this unit. The Model 3600 has 16 independent channels, a front panel touch screen, computer control capabilities and a built-in calibrator. In addition, users can quickly monitor on an external oscilloscope the activity on any two channels.

This product is currently out of stock and unavailable.

16-Channel Extracellular Amplifier with Headstage Model 3600

Multiple instruments will be controllable by a single computer program, enabling the setting of critical parameters on as many channels as you need.
Compared to the Model 1800, the Model 3600 has:
  • More gain settings and increased gain range
  • More high pass filter settings and increased high pass range
  • More low pass filter settings and increased low pass range
  • TTL Control of instrument mode
  • Channel Monitors
  • Built-In Calibration signal
  • Common Reference Bus
  • Blanking
  • PC control capability
  • MATLAB® and LabVIEW SDK and drivers available
  • Less rack space utilized for 16 channels
Two different headstages are available. One is a microminiature headstage that can make simultaneous pseudo-differential recordings from 16 channels, and is smaller than a dime! The other can stimulate and record to any combination of the 16 channels.
Most of the on-board control screens, and the PC Compatible software, are very similar in design to those utilized on our Model 3500 16-Channel Amplifier (without headstage). Click on these links for additional information on the on-board screens and the PC program.
